Horizontal Plate Filter Synchronization via Single Motor Linkage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Horizontal plate pressure filters face challenges in achieving even movement and level orientation of head and filter plates, leading to potential jamming and damage due to uneven load distribution and synchronization issues with hydraulic actuators.
Innovation Solution
A horizontal plate pressure filter design utilizing a single electric motor mechanically coupled to multiple positions of an opening mechanism ensures synchronized and level movement of the head plate, eliminating uneven movement and unlevel orientation by using an electric motor with a gearbox and pulley arrangement to transmit opening and closing movements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If hydraulic actuators are used for opening and closing filter chambers, then good force-weight ratio and position control are achieved, but synchronization of multiple actuators becomes difficult and expensive
Solution Approach 1:
The patent combines multiple actuation points into a single mechanical linkage system driven by one electric motor. The linkage mechanism (comprising levers, connecting rods, or belt-pulley systems) distributes the motion from a single motor to multiple filter plates, ensuring they open and close simultaneously without requiring complex synchronization control for each actuator.
Solution Approach 2:
The patent introduces a mechanical linkage system as an intermediary between the electric motor and the filter plates. This linkage mechanism translates the rotational motion of a single motor into coordinated linear motion at multiple points, acting as a mediator that ensures synchronized movement without requiring direct control of each actuator.
2Reliability
If multiple hydraulic actuators are used for opening and closing, then even load distribution is achieved, but uneven movement and unlevel orientation cause jamming and damage
Solution Approach 1:
The patent merges multiple actuation functions into a single motor-driven linkage system. This ensures that all filter plates receive identical motion commands simultaneously, preventing uneven movement and unlevel orientation that would otherwise cause jamming or damage to the mechanical components.
Solution Approach 2:
The patent segments the motion transmission path into multiple identical linkage branches, each connecting the central motor to a different filter plate. This segmentation ensures that each plate receives the same motion input, maintaining even load distribution and preventing harmful uneven movements.
3Adaptability or versatility
If separate actuators are used for opening/closing and sealing, then each function is optimized, but device complexity and cost increase
Solution Approach 1:
The patent makes the single electric motor-driven linkage system perform multiple functions: it simultaneously provides the opening motion, closing motion, and positioning for sealing. The same mechanical linkage that moves the plates apart for opening also controls their return for closing and ensures proper alignment for sealing, eliminating the need for separate actuator sets.
Solution Approach 2:
The patent combines the functions of opening actuators, closing actuators, and positioning mechanisms into a single integrated motor-linkage system. This merging reduces the total number of actuators while maintaining the ability to perform all required functions through coordinated motion of the linkage mechanism.
